Long, Director 4Ps .,� <br /> Division of Minerals and Geology 1� <br /> Department of Natural Resources C; .., ®;;,1�9 <br /> 215 Centennial Building c- <br /> 1313 Sherman Street _ <br /> Denver, Colorado 80203 <br /> Re: Coal Basin Mine, Mid-Continent Resources <br /> Dear Mr. Long: <br /> The Office of Surface Mining Reclamation and Enforcement (OSM) has reviewed all of the <br /> available documents regarding the variance for placing 4 feet of cover over coal waste <br /> piles. The review was conducted to determine compliance with Federal regulation 30 CFR <br /> 816.83(c)(4) and Colorado regulation 4.10.4(5). <br /> Based on the submitted material, it is OSM's opinion that the demonstration for the Sutey <br /> Pile is adequate and meets the demonstration requirements of the Federal and the State <br /> program. This pile should be reclaimed in accordance with the approved reclamation plan. <br /> However, for the remaining two piles, the Old Coal Refuse Pile and the Rock Tunnel <br /> Waste Pile, there is insufficient information to make a decision. Therefore, at this time, <br /> Title V regulations as well as the approved State program require that 4 feet of material be <br /> placed on the two piles. <br /> It is OSM's opinion that if the chemical composition and the compaction of these two piles <br /> are similar to that of the Sutey Pile, then the less than 4 feet of material requirement could <br /> be waived. If this affirmative demonstration is made, then OSM believes, at a minimum, <br /> these piles would have to be covered to a depth, using the same criteria, as the Sutey <br /> Pile. In other words, it must be demonstrated that the two piles have similar <br /> characteristics of the Sutey Pile in order to apply the variance to the two piles. <br /> If you have any questions, please call me at (505)766-1486. <br /> Sincerely, <br /> Robert H. Hagen, Director <br /> °� Albuquerque Field Office <br />
